Quick facts • CP is the most common physical disability in childhood • CP occurs in approximately 1 in 700 live births, in high income countries • It is caused by an injury to the developing brain, which mostly happens before birth • There is no single cause but researchers can identify a number of factors that may lead to the brain injury • Babies can now be diagnosed as at ‘high risk of CP’ at three months of age • There are many evidence-based interventions for CP and new international clinical guidelines will soon be available. www. worldcpday. org

Cerebral palsy (CP) is a physical disability that affects movement and posture • CP is an umbrella term for a group of disorders that affects a person’s ability to move • CP is due to damage to the developing brain before, during or after birth • CP affects people in different ways. It can affect body movement, muscle control, muscle coordination, muscle tone, reflex, posture and balance. • Although CP is a permanent life-long condition, some of these signs of cerebral palsy can improve or worsen over time • People who have CP may also have visual, learning, hearing, speech, epilepsy and intellectual impairments. www. worldcpday. org

Causes of cerebral palsy Cerebral palsy (CP) is the result of a combination of events either before, during, or after birth that can lead to an injury in a baby’s developing brain • There are multiple causes of CP – but a series of ‘causal pathways’, i. e. a sequence of events that combine to cause or accelerate injury to the developing brain. • About 45% of children diagnosed with CP are born prematurely • For most babies born at term with CP, the cause remains unknown • Only a small percentage of CP is due to complications at birth (e. g. asphyxia or lack of oxygen). www. worldcpday. org

Risk factors do not cause CP. However, the presence of some risk factors may lead to an increased chance of a child being born with CP. Some risk factors for cerebral palsy have been identified. These include: • premature birth (less than 37 weeks) • low birth weight (small for gestational age) • blood clotting problems (thrombophilia) • an inability of the placenta to provide the developing foetus with oxygen and nutrients • bacterial or viral infection of the mother, foetus or baby that directly or indirectly attacks the infant’s central nervous system • prolonged loss of oxygen during the pregnancy or birthing process, or severe jaundice shortly after birth. www. worldcpday. org

Diagnosis CP can sometimes now be diagnosed early, so interventions can start as soon as possible Babies can now be assessed as being at ‘high risk of cerebral palsy’ as early as 3 -5 months of age. The most sensitive tools are: • General Movements Assessment in babies <20 weeks (corrected) - 95% predictive • Neuroimaging • Hammersmith Infant Neurological Assessment (HINE) - 90% predictive See CP: Diagnosis and Treatment poster at www. worldcpday. org

Diagnosis (cont) Risks for Cerebral Palsy Neuroimaging Assessing Motor Development www. worldcpday. org

Motor types SPASTIC: 80 -90% DYSKINETIC: 6% ATAXIC: 5% MIXED TYPES Most common form of CP. Muscles appear stiff and tight. Arises from damage to the Motor Cortex. Characterised by shaky movements. Affects balance and sense of positioning in space. Arises from damage to the Cerebellum. Characterised by involuntary movements such as dystonia, athetosis and/or chorea. Arises from damage to the Basal Ganglia. A number of children with CP will have two motor types present, e. g. spasticity and dystonia. www. worldcpday. org

Parts of the body Cerebral palsy can affect different parts of the body. For example, for people with spasticity: Quadriplegia/Bilateral Spasticity Both arms and legs are affected. The muscles of the trunk, face and mouth are often also affected. Diplegia/Bilateral Spasticity Both legs are affected. The arms may be affected to a lesser extent. Hemiplegia/Unilateral Spasticity One side of the body (one arm and one leg) is affected. www. worldcpday. org

Gross motor skills The gross motor skills of children and young people with cerebral palsy can be categorised into 5 different levels using a tool called the Gross Motor Function Classification System (GMFCS) Expanded and Revised, available from Can. Child in Canada. GMFCS Level IV GMFCS Level III GMFCS Illustrations 6 -12: © Bill Reid, Kate Willoughby, Adrienne Harvey and Kerr Graham, The Royal Children’s Hospital Melbourne. GMFCS Level V www. worldcpday. org

Manual ability At least two thirds of children with cerebral palsy will have movement difficulties affecting one or both arms. Almost every daily activity can be impacted. Eating Dressing Writing Catching a ball The ability of children from 4– 18 years old with cerebral palsy to handle objects in everyday activities can be categorised into 5 levels using the Manual Ability Classification System (MACS).

Associated impairments Children with CP may also have a range of physical and cognitive impairments 1 in 4 3 in 4 1 in 4 is unable to walk is unable to talk experience pain has epilepsy has a behaviour problem 1 in 2 1 in 10 1 in 4 1 in 5 has an intellectual disability has a severe vision impairment has bladder control problems has a sleep disorder has saliva control problems www. worldcpday. org

Focus for child development The 'F-words' focus on six key areas of child development that are vital to all children with CP. More details at https: //www. canchild. ca/en/research-in-practice/f-words-in-childhood-disability www. worldcpday. org

Treatment considerations PAIN HIP DISPLACEMENT 3 in 4: Treat to prevent sleep and behavioural disorders 1 in 3: 6 -12 months hip surveillance using x-ray INTELLECTUAL DISABILITY NON-VERBAL 1 in 2: Poorer prognosis for ambulation, continence, academics 1 in 4: Augment speech early NON-AMBULANT EPILEPSY 1 in 4: Independent sitting at 2 years predicts ambulation 1 in 4: Seizures will resolve for 1020% of children www. worldcpday. org

Treatment considerations (cont. ) BEHAVIOUR DISORDER BLINDNESS 1 in 4: Treat early and ensure that pain is managed 1 in 10: Assess early and accommodate BLADDER INCONTINENCE NON-ORAL FEEDING 1 in 4: Conduct investigations and allow more time 1 in 15: Assess swallow safety and monitor growth SLEEP DISORDER DEAFNESS 1 in 5: Conduct investigations and ensure pain is managed 1 in 25: Assess early and accommodate www. worldcpday. org

Future • With the support of parents, families, communities, governments and health professionals, children with cerebral palsy will lead healthy and contributing lives • The future is bright, with international efforts to collaborate in research, practice, education, technology and social action by, and for, people with CP • Join World Cerebral Palsy Day and become part of this global community to improve the lives of people with CP around the world.
